Halophytes are plants that exhibit high salt tolerance, allowing them to survive and thrive under extremely saline conditions. The study of halophytes advances our understanding about the important adaptations that are required for survival in high salinity conditions, including secretion of salt through the salt glands, regulation of cellular ion homeostasis and osmotic pressure, detoxification of reactive oxygen species, and alterations in membrane composition. To explore the mechanisms that contribute to tolerance to salt stress, salt-responsive genes have been isolated from halophytes and expressed in non-salt tolerant plants using targeted transgenic technologies. In this review, we discuss the mechanisms that underpin salt tolerance in different halophytes.
盐生植物是表现出高耐盐性的植物，使它们能够在极端盐碱条件下生存和繁茂生长。对盐生植物的研究增进了我们对在高盐度条件下生存所需的重要适应性的理解，包括通过盐腺分泌盐分、调节细胞离子稳态和渗透压、清除活性氧以及改变膜组成。为了探索有助于耐受盐胁迫的机制，已从盐生植物中分离出盐响应基因，并使用靶向转基因技术在不耐盐植物中进行表达。在这篇综述中，我们讨论了不同盐生植物耐盐性的基础机制。
